Now that my memory has loosened up, I recall that what I did when I went through this exercise on my last rig about 15 years ago to beef up my tires was to climb up a step in load rating. But in this case, it looks like I'm already at the top load rating for this size tire, so I guess there's not much I could do to get a more robust compatible tire. (Well, other than change brands, of course -- I'm doing this precisely to get rid of the Trailer Kings.) I will look forward to hearing about those "steel cased" tires if someone responds.
I see those Carlisles available at
tirebuyer for $86, a far cry from the
Goodyears that are running around $135 each. I'm a little surprised at this, but if there's some massive discrepancy in the specs, I'm missing it.
Thanks.
